Extra information..
for 'Hi/Low', means both your low and high beam is HID..
however for 'Hi' only means u can either put high beam or low beam as HID, while the one which is not HID will be your normal beam (yellow as default).
I bought a 'Hi' HID and now my high beam is yellow, and my low beam is HID...
normally ppl will do low beam as halogen bulb and high beam as HID, because of my lights tat are made from 'brand ayam', and unable to adjust well, so my High beam = low beam glare.
u can try go to exterior and body section look for ppl who selling Hi only, which will be cheaper then Hi/Low..
price is differ from brands and quality...i bought mine rm280 full set 1 and half years ago..
U need a suitable size example : H1,H2,H3,H4,etc etc..if u do not know tat, u can ask the seller which u're buying from..
